This invention relates to surgical spray devices, and more particularlyto a portable mechanism adapted to be employed as a vaginal douche inconjunction with bottled carbonated water.

A main object of the invention is to provide a novel and improvedsurgical spray mechanism which is simple in construction, which isadapted to be employed with conventional carbonated water bottles, andwhich is designed for direct application and use with bottles in whichcarbonated water is widely sold.

A further object of the invention is to provide an improved vaginaldouche mechanism which is inexpensive to manufacture, which is reliablein operation, which automatically regulates the pressure of thecarbonated water employed with the device, and which is very easy tomanipulate.

Further objects and advantages of the invention will become apparentfrom the following description and claims, and from the accompanyingdrawings, wherein:

Figure 8 is an enlarged perspective view of the valve plunger employedin the surgical spray device of Figures 1 to 7.

Referring to the drawings, the surgical spray device-is designatedgenerally at I I and comprises a head member I2 of suitable rigidmaterial, such as plastic material, having secured thereto theelongated, curved, spray tip I3 of similar rigid material. The head I2is provided with a sleeve portion I4 defining a cavity l5 adapted toreceive the mouth portion of a conventional carbonated water bottle I 6in the manner shown in Figures 1 and 3, the sleeve member I4 beingformed at its rim with diametrically opposed, inwardly extendinggripping lugs I'I, I1, and being divergently slotted at I8, t8 adjacenteach inturned lug IT to provide a degree of resiliency for the grippinglugs I! and to enable said lugs to snap over the usual curved mouthportion I9 of a bottle to secure the mouth of the bottle in the sleeveportion I4.

Designated at 2B in an annular bulb of elastic deformable material, suchas rubber or the like, said bulb being formed with the annular baseflange 2| which is received in the bottom of the sleeve portion I4 andwhich is clampingly engaged I by a fiat, C-shaped, resilient ring 22seated in an annular groove 23 formed in the lower portion of theinterior wall surface of sleeve member l4, said ring 22 exertingclamping pressure on the annular flange 2| and tightly securing the bulb20 in axial position in the cavity I5. Designated at 24 is a plungerhaving an enlarged body portion 25 and a stem portion 26. The plunger 24is arranged coaxially inside bulb 2!} with the stem portion 26 extendingslidably through head I2, as shown in Figure 3. Said head is formedadjacent th enlarged body portion 25 of the plunger with a cylindricalcavity 27 allowing plunger 24 to reciprocate along its axis. Secured tothe end of the stem 23 is a button element 28, and surrounding the stem26 and bearing between button element 28 and head I2 is a rubber springwasher 29 biasing the plunger 24 downwardly, as viewed in Figure 3.Downward movement of the plunger 2:1 is limited by the shoulder 30defined at the end of enlarged portion 25. Axially secured to the topend of the enlarged portion 25 is a rod 3| having secured to its end thevalve element 32 adapted to seat on the end of the annular bulb 20, therod 3| extending through an opening 33 formed in the tip of the bulb. Asshown in Figures 3 and 8, the main body portion 25 of the valve plungeris formed with the longitudinal flutes 34, 34.

Ihe spray tip I3 is formed with the passage 35 which communicates with apassage 36 formed in the head i 2 and which connects passage 35 to thecavity 21 of said head.

In using the device, the head I2 is first engaged over the mouth of abottle I 6 of carbonated water, the bottle mouth being received in thecavity I5 and being lockingly engaged by the gripping lugs I1, I! in themanner above described, the bulb 20 being received inside the bottlemouth. The pressure of the carbonated water acts on the valve element32, and said pressure combines with the biasing force of spring 29 tocause the valve element 32 to seat on the bulb tip and exert substantialcompressive force on the bulb. The compressive force of the valveelement 32, acting axially on the bulb 20, causes said bulb to expandlaterally against the inner surface of the bottle mouth and to sealinglyengage said inner surface, as well as exerting clamping force thereonrelative to the adjacent external portions of the sleeve I4. It will benoted that the pressure of the carbonated water. acts on the sidesurfaces of the bulb 20 as well as on the valve element 32, and tends,to some degree, to oppose the lateral expansion of said bulb produced bythe compressive axial force imposed on the bulb by valve element 32.Said axial force is provided by the combined efiect of the spring 29 andthe pressure inside the bottle. If, however, the pressure inside thebottle is excessive, it will be sufiicient to prevent the valve element32 from sealingly engaging he tip of the bulb, and hence, will allow thegas under high pressure to escape from the bottle through opening r a i21, passage 3 n p sa 35,. unt l 3 the pressure has diminishedsufficiently to allow valve element 32 to seat on the tip of the bulb.

In using the device, the button element 28 is pushed inwardly, causingthe valve element 32 to be elevated with respect to the tip 2|] and toallow the carbonated water to pass through opening 33, cavity 27,passage 36,and passage 35, and

to issue from the tip of the nozzle E3 in the form of a spray.

It will be noted that when the spray device is attached to abottle, thebulb 2c is narrowed and elongated by depressing the button element 28,the end of the enlarged body portion 25 of the valve plungerengaging thetip of the bulb and causingsaidbulb to be stretched and narrowed. Thisallows'the clamping lugs H, H 'to'snap past thecurved portion it of thebottle neck as the sleeve I4 is engaged over theneck of the bottle.Releasing the button element then allows the bulb to assume its normalshape, thereby sealing the bottle opening and at the same time allowingthe valve element 32 to sealingly engage the tip of the bulb 2t andclose the opening thereof. As above explained, whenever the pressure inthe bottleexceeds a'predetermined value, said pressure acts on thebulbzc until the bulb is distorted to such a degree that the valveelement 32 no longer seals the opening $3, allowing the gas underlhighpressure to escape through the device 'until the'pressure dropssufiiciently to allo'wthe tip ofthe bulb to be engaged by the valveelement 32. The limiting value of pressure may bereadily adjusted byemploying a suitable length of the valve plunger, and more particularly,by adjusting the length between shoulder .30 and valve element '32.

After the mechanism has been attached to the carbonated water bottle, asabove described, and after the excess pressure has been releasedautomatically, as above explained, the spray nozzle tip [3 is insertedinto the vagina and the release button 28 depressed, allowing thecontents of the bottle to be discharged.

The action of the'ga escaping from the bottle l6 may be made morerapidand may be made more active by agitating the bottle it after thespray attachment has been secured thereon.

While a specific embodiment of an improved surgical spray device hasbeen disclosed in the foregoing description, it will be understood thatvarious modifications within the spirit of themvention may occur tothose skilled in the art. Therefore, it is intended that no limitationsbe placed on the invention except as defined by'the scope of theappended claims.
